PROCESS QFAND APPARATUS FOR COATING BARBED FENCE-WIRE WlTH METAL.

SPECIFICATION forming part of I Letters Patent No. 264,535, datedSeptember. 19, 1882 Application filed October 21, 1880. (No model.)

To all whom it may concern:

Be it known that I, EDWIN H. HILL, of the city and county of Worcester,and Commonwealth of Massachusetts, have invented certain new and usefulImprovements in the Process of and Apparatus for Coating BarbedFence-Wire with Metal and Cabling Barbed Wire, as hereinafter described,and also certain improvements in the mechanism for car- 1'0 ryin g outsaid mode or process, orin aid thereof; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to .the accompanying drawings, forming a part of thisspecification, and

in Which- V r Figure 1 representsa top or plan view-of so much of amachine for zinc-coating or tinning barbed fence-wire as isnecessary toillustrate my present invention; and Fig. 2 represents a side view,looking in the direction of arrow 1, Fig. 1.

. The nature of my invention consists, first, in a method of coatingwith metal and cabling barbed wire, as hereinafter described; and,

2 5 second, in an improved apparatus or machine for facilitating suchmode or process, as hereinafter described.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it more in detail.

Inthe drawings, the part marked A represents the furnace, and B thezinc-receptacle, all of which parts may be made in the usual 5 mode ofmaking zinc-coating furnaces.

(land D represent the two spools of wire,

supported upon suitable journals in the ends of standards E E,projecting from the front of the furnace 'A, as fully indicated in the40 drawings.

F and spool O the unbarbed wire G, and these strands of wire F and G arepassedforward and down underthe grooved guides 11 b on the lower ends ofhinged levers c and d, said levers beingjournaled at), so as to swingfreely thereon. Lever cis shown swung back in Fig.

2 for the purpose of more fully representing the course of the barbedwire as it passes through the metal coating and cleaning appa- 5o ratus.The barbed wire F, after passing under around a pulley, Q, on its lowerend.

Spool D contains the barbed wire its grooved guide I), is drawn upthrough a ro- ,tating tube or cylinder, H, the lower end of which tubeor cylinder ismade flaring to preventthe ends of the barbs a fromstriking against the lower edge of said tube or cylinder H in theirpassage from the molten-metal bath to the grooved guide-roll I, andthence over the sprocket-wheel J to the spool K in the twistingapparatus L, and which twisting apparatus may be made in any of thewellknown forms heretofore in use for twisting and cabling barbed wire.

The molten metal in receptacle B, when the apparatus is in use, iscoveredby preference with a'thin coating of finely-broken charcoal, 6and the tube or cylinder H is also filled with finely-broken charcoal,sand, or some'other similar material, and which charcoal, sand, or othersimilar material is prevented from working out at the bottom of tube orcylinder H in consequence of the greater specific gravity of the moltenmetal, which always covers the lower end of said tube or cylinder H. l

Tube or cylinder H is provided with a pulley, M, around which passes abelt or band, N, from a pulley, O, on the upper end of shaft P, which inturn is driven by a belt passing Cylinder or tube H may be driven,however, in any other convenient manner, at a moderate speed, for thepurpose of moving the charcoal, sand, or other similar substance withwhich said tube is filled around and against the points of barbs a,thereby working oft all surplus metal before it cools, and as a resultof such operation the barbs a, on leaving tube H, are smooth, and theirpoints sharp and free from bunches of adhering metal, which would oth--erwise be the case. Then, again, a great saving of metal is made, sincethe particles (after being abraded or removed from the barbs by theaction of the moving charcoal or sand) work down into the receptacle Band mingle with the inelted mass for use again.

The unbarbed wire G, after passing under 5 its grooved guide I), thesame as its fellow wire,

F, passes up over grooved guide-r0111, after which both wires aretwisted or cabled together by means of twister L as they are drawn uponand over sprocket-wheel J to reel 10o K, in the usual manner of reelingand twisting barbed wire composed of two or more main strands.

It will be observed that the wire strands F and G run separate and apartfrom each other until after they leave the grooved guide-roll I, andhence, while the barbs are fastened to the wire upon which they arecoiled, the two main wires are not united together by the molten metal,which has cooled by the time the wires are drawn over grooved guide-rollI, and they therefore retain as much, if not more, spring and elasticityas ordinary cabled wire, and which is not the case when cabled wire isrun through molten metal, since by such operation both strands areunited together and rendered stitt' and comparatively rigid.

In lieu of the cylinder H, any mere equivalent device may he used, andif the part or cylinder H were given a motion by vibrating the same, orother jarring motion, the points of the barbs might be Cleaned, andthat, too, without departing from the principle of my invention.

Before passing the wires to thebath of molten metal they may he runthrough a bath of boiling sal-ammoniao or a bath of muriatic acid; but Iprefer to dip the spools or reels of wire 0 D into a bath of boilingsal-ammoniao before they are placed into the positions shown in thedrawings.

Hafingdescribed myinventiomwhatIclaim, and desire to secure by LettersPatent, is-

1. The method of coating with metal and ca bling barbed wire, ashereinbefore described, consisting of running the strands separately orapart through a bath of molten metal, and then passing the barbed wirethrough a mass of charcoal or sand having a stirring or barbcleaningmotion for removing the surplus metal from the barbs and barb-points,substantially as described, and then, after the metal coating hassufficiently cooled to prevent a union between the separate main strandsof wire, cabling or twisting the metal-coated wires together, for thepurposes stated.

2. In an apparatus for coating barbed wire with metal, the combination,with the receptacle B for containing the molten metal, of a charcoal orsand receiver or receptacle, H, substantially as and for the purposesset forth.

3. In an apparatus for coating barbed wire with metal, the combinationof receptacle to contain the molten metal with grooved guides fordirecting the separate wires into the molten metal, a charcoal or sandreceptacle, through which the barbed wire passes after leaving the bathof molten metal, for cleaning the barbs and barb-points from surplusmetal, substantially as described, and a twisting, cabling, and spoolingmechanism, for the purposes set forth.
